50551 digital fieldmeter is sold separately.
Inspection
Remove the kit from the carton and inspect for damage. Each
kit includes:
1 50551 Digital Field Meter
1 Isolated Plate Assembly
1 ±1000 Volt Charger
1 9 Volt alkaline battery (installed)
1 Carrying case
Taking Balance Measurements
The Portable Ionization Test Kit has been designed to match
the compact size and hand held convenience of the 50551
Digital Field Meter. Use the following procedure to verify the
balance of air ionization equipment. This quick and easy
procedure will help determine if the piece of ionization
equipment is working within the manufacturer's specifications
or user requirements.
It is extremely important that ionizers
be checked regularly for balance. An ionizer operating in
an out-of-balance state can damage sensitive electronic
componets or assemblies.

Description
The Desco EMIT Portable Ionization Test Kit allows the 50551
Digital Fieldmeter to be used to monitor the balance of
ionization equipment. The test kit also includes a Charger used
to place a 1000V charge on the isolated adapter plate
assembly, making it possible to also measure the neutralization
performance of air ionization equipment. The 50552 Test Kit
was designed to be used in conjunction with the 50551 Digital
Fieldmeter, providing a highly portable and cost effective
means of verifying the performance of a wide variety of
ionization equipment.
NOTE:
The 50551 Digital Fieldmeter is designed to operate
only with the 50552 Portable Ionization Test Kit. It is not
compatible with other brands.
Currently there are no established standards describing a
periodic verification device or procedure for air ionizers. The
Desco EMIT Portable Ionization Test Kit has been designed to
make measurements that correspond to those made by using
a charged plate analyzer and ESD Association's Standard 3.1.
While the Ionization Test Kit provides convenience and
portability, it does not meet all of the requirements of the ESD
Association Standard. We recommend our Charged Plate
Analyzer if precise measurements are required.
The Portable Ionization Test Kit includes a slide-on isolated
plate assembly, a ±1000 volt charging unit and a durable
thermoplastic carrying case with custom cut-outs for all of the
